Distribution of subtle reservoirs in s_3 formation of Dongpu Sag

Open publisher page 0 citations

Abstract

Sequence stratigraphy study shows that Dongpu Sag is an inland salt lake basin with many nearby provenances and sedimentation centers. Reservoirs distributed around the main hydrocarbon kitchen and formed three favorable accumulation zones: eastern sag belt (winding round Pucheng-Qianliyuan sag), western sag belt (winding round Liutun-Haitongji sag) and Puwei Ring sag belt (winding round Pucheng-Weicheng sub-sag belt). This understanding has been proved by exploration practice in recent years.
